What should the engine temperature gauge read at operating temp on a 1997 Tahoe?

The engine temperature gauge on a 1997 Chevy Tahoe, when at optimal operating temperature, should be slightly above the halfway mark, but not pegged all the way to the "H" or in the red zone. Think of it as being in the upper portion of the normal range, about ⅔ of the way up from the "C" (cold) mark. The exact position might vary slightly depending on ambient temperature and driving conditions.
